Fluorid thallitý je anorganická sloučenina s chemickým vzorcem TlF3.

Příprava

Fluorid thallitý lze připravit reakcí oxidu thallitého s fluorem, fluoridem boritým, nebo fluoridem siřičitým:[2][3]

2 Tl2O3 + 6 F2 → 4 TlF3 + 3 O2

Vlastnosti

Fluorid thallitý je bílá pevná látka, která je velmi citlivá na vlhkost. S vodou okamžitě reaguje za vzniku černé pevné látky:[2][4]

TlF3 + 3 H2O → Tl(OH)3 + 3 HF

Při zahřívání na vzduchu se fluorid thallitý rozkládá, ale v atmosféře fluoru se taví.[2] Krystalizuje v ortorombické soustavě typu fluoridu ytterbitého s prostorovou grupou Pnma (Číslo 62)[5] s parametry mřížky a = 5,81 Å, b = 6,97 Å, c = 4,84 Å.[6]
